Cell Membrane Dialysis Tubing
Diffusion difference: Diffusion (D) is the process of passive (without loss of energy) movement of any substance from higher concentration to the lower concentration of that substance. D depends on the membrane and varies from membrane to membrane. There is no diffusion across dialysis tubing. Dialyzer (D) membranes vary as well so they is no accurate way to correlate the rate of D from a biological membrane and D. ...Read more
Simple answer is that it is a medical technology used primarily to provide an artificial replacement for lost kidney function in people with renal failure. Hemodialysis remove wastes and excess water from the blood by circulating blood outside the body through an external filter, called a dialyzer. Blood and dialysate flow through in opposite directions and the ...Read more
Talk to doctor: What kind of dialysate, what kind of mebrane, all can and should be discussed with your renal doctor. ...Read more
It's complicated: Cholesterol stabilizes membranes and keeps them from melting / breaking down at both high and low temperatures but by different mechanisms. This is some serious physical chemistry. Ignore all the "pop" accounts you'll find online and ask a teacher at a good junior college. ...Read more
Yes: There's a variety of different toxins secreted by the salivary glands of venomous snakes. Depending on the species, some venoms attack nerves(neurotoxins), heart muscle(cardio toxins), blood cells (hemotoxins), cell membranes (phospholipases). The latter would cause lysis of cell membranes. ...Read moreSee 1 more doctor answer
I read viruses can steal the cell membrane of a cell after it kills it to blend in and not be detected by your body. How does your body then find it?
Temporary housing: A virus does move into a cell and take over its little factory sites to make new virus (not hide). After its presence has destroyed the integrity of that host cell, the cell wall breaks down and all the new viruses enter the blood to find new cells and start over. Your immune system (and fever response) detect the new viruses and work to kill them off.This is considered why your temp fluctuates ...Read more
I had IntraLasik done 2 months ago, epithelium came off during the surgery and new cells didn't want to grow properly and stick to membrane.Why?
If I am thinking of doing a non directed donor kidney donation, is there an advantage to doing it now or waiting 1/2 yrs? At the rate of stem cells and dialysis will it no longer be neccisary in 2 yrs
A noble decision: You are very sweet to consider donating a kidney. As you know organs can save lives and no matter when, it will benefit someone. Make sure you are in good health yourself and that none of your family members have kidney disease. When you have only one kidney left also avoid extreme sports and sports that involve blunt trauma/falls. To decide when and where is all up to you. ...Read moreSee 2 more doctor answers
What happens to the plasma membrane of the red blood cells of humans with liver disease to cause the formation of acanthocytes? Thank you.
Change in lipids: The liver is responsible for general metabolism in the body, and the plasma membrane has a complex collection of lipids that are responsible for its "fluidity" and shape. It is believed that the apolipoproteins are abnormal in liver disease and cause fragility of the rbc membrane causing fragmentation and formation of acanthocytes.
